Z-2300 noisy speaker

If it sounds like static, and the bass really effects the sound it is most likely going to blow.
I would suggest taking it easy on the volume or switching your volume settings so its more on the left speaker than that right, but still with sound coming out the right one. Just so you don't blow it as fast.

a simple aa battery and a couple pieces of wire is all you need,connect wires to the speaker and then by attaching the wires to the end of the battery you can make the speaker move. when the speaker moves out follow the wires just as they are on the battery . the positive side of the battery will be the positive to the speaker. hope this helps.

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

Yes, you can check left speaker by replacing it or by interchanging with the rightside speaker. If the speaker is okay, then check for faulty amplifier circuit board. Don't forget to check the dirty EP socket or banana pin for leftside speaker.

Depends what the real problem is.

Is it related to certain sources only - try new or reseated cables,swap it to a different input; single channel - swap to isolate; or certain controls that have become noisy? A shop might be able to get some tuner cleaner into them.

On new systems, like the one you bought to replace old one: grey and white are front, purple and green are rear. New wires should be labelled or shown on diagram on radio body. Stripes indicate negative side of speaker.

On your old loom: cut back behind plug, and strip wires at ends. Isolate power and grounds, and any that go hot EVER! Now checking just the remaining wires, use a AA or 9-volt battery, and touch pairs of wires to opposite poles of the battery. If you touch two that go to the same speaker, you will hear a slight static sound at that speaker: label these for that speaker, and so on. Once you get the pairs seperated and labelled by speaker location, the negs will be the striped ones, though you may not find they all have stripes. once you pair them, test in both polarity positions, the correct one will sound better right away. Should be able to reach max volume with little buzz or distortion. If not switch pow and neg sides. Hope this helps, TT

My speaker did the same, brand new out of the box, but I ran TomTom Home and it upgraded my firmware. Since then, no issues, and perfect clarity

Sounds like the left channel in the built-in amplifier went out or possibly damage in the connector or cabling. Quick test to eliminate the PC is to connect another set of working speakers or headphones into the PC speaker jack without making any changes. If it works w/o problems then it?s the speakers. You can try plugging the speakers back into your PC and while playing something start wiggling the left channel cables and the main cable that goes into the PC. In particular pay attention to stress points like connectors. If that turns up nothing and you have the appropriate tools and skills you can open the speakers up and test out the solder points for the cables as well. As always make sure your warranty has expired completely before you open them up or start cutting away. Let us know if you have any other questions and please don?t forget to rate this post.

Have you tryed a differant audio input on another set or on that same set. Are the audio cables good?? If all this is ok then the D/A converter inside the unit is defective and most likely it wont pay to repai sorry
